Application filed March 28, 1901 Serial No. 53,337.

To all whom it may concern:

Be it known that 1, CHARLES H. SHEPARD, a citizen of the United States, and a resident of the borough of Brooklyn, city of'New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type vVriting Machines, of which the following is a specification.

This invention relates to line feed devices 'of type-writing. machines. 3

The. main object of the invention is to enable the operator to feed the paper at will either through ordinary line spaces, by means of the usual line spacing mechanism, orthrough special line spaces, by means of a novel mechanism, so that when writing upon ruled paper the line-feeding movements may be made to agree with the spacing of the ruled lines upon the paper, so as to avoid the necessity of re-adjusting the paper upon the platen at the beginning of each line of writing, in order to bring a ruledhne thereon into position for receiving the type impressions.

Another object is to facilitate the writing of one or more characters out of line when desired, as in writing fractions or exponents.

My invention contemplates the employment of a clutch for rotating the platen, means for variably limiting the throw of the clutch and platen, so that minute variations in the line feed of the paper may be produced, and means for preventing accidental -movementof the platen and paper.

The invention consists in certain combinations of devices, featuresv of construction and arrangements of parts, all as will be more fully hereinafter set forth and particularly pointed out in the concluding claims.

In the accompanying drawings, Figure 1 is a front elevation of the platen of a Remington No. 6 typewriting machine, showing'my im provements connected therewith, the platen frame being shown in section. Fig. 2 is an end elevation of the novel platen rotating mechanism, the clutch being shown in its normal position of disuse. Fig. 3 is a view similar to Fig. 2, but illustrating the manner of rotating the platen by means of the clutch. Fig. '4 is a perspective view of the clutchlever detached. Fig. 5 is an elevation of the righthand end of the platen frame and showing the ordinary line-feed devices.

In the several views similarparts are designated by similar numerals of reference, and portions of the machine not pertinent to the invention are omitted.

- 1 designates the usual revoluble platen, mounted upon a shaft 2, which is journaled in the end bars 3 and 4- of the platen frame. Upon the right-hand end of the platen is mounted a notched line space wheel 5, which is normally engaged by a detent roller 6, carried upon the forward end of a spring 7, secured to the platen frame. The ordinary line feed of the paper is produced by means of a lever 8, pivoted at 9 upon an arm 10 fixed to the platen frame, and carrying at its upper end a pawl 11 which is adapted to engage the teeth of the line space wheel.

The detent roller 6 may be disengaged from the line-space wheel by a release cam 12, having a handle or lever 13 and pivoted at 14 upon the forward end of a shoe 15, which is pivoted between its ends upon the axis 16 of the detent roller. Said cam 12 is adapted toengage a fixed pin-17, which projects in wardly from a standard 18, rigidly secured upon the end bar 4 of the platen. When the cam lever is in its normal depressed posi-' tion, the roller engages the teeth of the line space wheel, as indicated in dotted lines at Fig. 5, and prevents accidental rotation of the platen; but when said lever is swung up to the full line position at said figure, the cam 12 is caused to work upon the pin 17 and lift the forward end of the shoe, the rear end of which bears at 19 upon the periphery of the platen, thus frictionally opposing the rota tion thereof. By this construction, it will be seen that the platen when released from the control of the ordinary detent 6, is simulta neously placed under the control of the friction shoe, so that its accidental rotation at this time is prevented.

The devices thus far described are in common use upon said Remington typewriting machine.

At the left-handend of the platen, T pro vide the so-called universal or fractional line spacing mechanism comprising a gripper 21 which is adapted to clutch the periphery of the usual metallic platen head 20. The gripper is pivoted on an arm 22, and the latter is mounted by means of a sleovelike. device 23 upon a hub 251, which is usually formed intogral with the platen'head 20, whereby the arm and gripper are enabled to swing together about the platen axis. Said gripper overhangs the platen head, and. 18 provided with an upwardly projecting handle or lever 25; As will be seen at Fig. 2, the working end of the gripper projects a short distance to the rear of a line joiningthe platen axis 2 and the pivot 26 of the gripper, so that when the handle 25 is pressed rearwardly and the gripper is tipped downwardly, the point of contact of the line joining the axes 2 and 26, and the grip atter with the platen head is close to said per is,crowded up the rise or crown of the platen head. By this-means the arm 22 becomes .clamped to the platen head, sothat further rearward movement of the lever 25 'causes the arm 22, the platen head and the platen to turn together bodily about the platen axis.

For returning the clutch to normal position, I provide a spring 27, one end of which is securedto the platen frame, as by a screw.

which istapped into an upwardly directed arm 32 also formed upon said sleeve 23, and is adapted to contact with the upper surface of the platen frame at a point forward of the axis 2, so as ,to limit the return movement of the clutch. The thumb screw 31 is provided with a binding nut 33.

It will be understood that the sleeve 23, arms 22, 30 and '32 constitute a frame which is pivoted to vibrate on the same center that the platen turns on and that the arms 30 and 32 of said frame extend said p vptal center.

In theusual operation of the machine, the handle 8 is vibrated so as to rotatethe platen on opposite sides of by meansof the notched line space wheel 5,

and produce ordinary line-feed of the paper. When'it is desired to produce a special linefeed of the aper, the cam lever 13 is thrown up to the 'ull line position at Fig. 5, thus causing the cam 12 to ride up on the fixed pin 17, and thereby turn the brake shoe about the pivot 16, so that the shoe is forced against the platen, and simultaneously casting off the line space check 6, the function of the latter being now performed by the brake shoe, Then the clutch lever 25 is pressed rearwardly, turning freely upon its pivot 26 until the toe of the gripper 21 bites the periphery of the platen head 20, whereupon, by a continued rearward. pressure upon the lever, the platen head and platen are rotated, as illustrated at Fig. 3, until the clutch is arrested by the stop 29 forcing the spring 27 into contact nary line s ace wheel.

with the platen frame. Then the lever 25 is released, and the spring 27, acting through the stop 29 and arm 30, restores the clutch to normal position, with the point of the screw 31 bearing upon the platen frame- It will be seen that by adjustin the screw 31 up or down, the movement 0 the parts back to normal position is made greater or less and hence at the active stroke of the clutch the feed of the platen and .paper is increased or diminished. The line spacing may be minutely varied.

In case ruled paper is used, the first ruled line thereon may be brought into re ister with the usual platen scale 84,.which is ac'ed just in front of the usual pressure rol er 35. Then the platen may be rotated by the lever 25, and the operator may determine, b inspecting the paper, whether or not it has con fed the exact distance neacessary to bring the second ruled line thereon into register with the scale. If the feed is too great, the. nut33 may be loosened and the screw 31 turned down, thereby shortening the stroke of the clutch mechanism until at each movement thereof the paper will feed the required distance. Having thus adjusted the throw of the clutch, the lever 13 may be temporarily turned down to normal position, thereby.

re-engaging the check'6 to the. line space wheel 5. Then the first ruled line upon the ruled line into register with the printing line paper is again adjusted into register with the 'Ioo upon the platen, which is indicatnd at A, I

Fig. 2. the detent 6 cast oii. Then the keys are operated to produce the type impressions, which fall upon the first ruled line upon the paper. When the line is full, the carriage is returned. to begin a new line, and'by a stroke of the lever 25 the paper is .fed so as. to bring the second "ruled line thereon into position Then the lever 13 is again raised and TIC for receiving the type impressionsm Thus the writing of the page may proceed. Should the line spacing prove a trifle incorrect, the

make as minute an alteration in the throwof the clutch as may be required It will be understood that the clutch-feeding mechanismis also of use when it is desired to space thelines u on unruled paper either a little more close 'y or a little more openly than is possiblewhen using the ordi- The latter, it will be understoo aiiords only a set spacing of the lines, dependent upon the. pitch of its teeth, while the clutch mechanism affords any desired special spacing. It will be perceived further that while using the ordinary line feeding mechanism, my novel clutch mech anism may be em loyed to advantage for eiscrew 31 may be adjusted. at any time so as tolease of the lever 25, the spring-controlled detent 6 serves to reposition the platen, so

that the Writing of the line may be resumed.

It will also be perceived that the screw 28 may be loosened and the spring 27 slipped off, the latter being provided with an open slot 36 for facilitating removal; andthereupon the arm 22 may be thrown idly back, until the stop 29 contactswith the platen frame; and from this initial position the lever may be pressed-forwardly, causing a'forwardly pro ecting toe 37 thereon to bite the platen head 20, so that further forward movement of the lever 25 may produce a reverse adjustment of the platen, thus adjusting the paper a trifle to-therear, so that one or more characters may fall a little above the line of writin thereon, as when writin the numerators of fractions, or exponents pon releasing the lever 25, the platen will be repositioned by the spring check 6, so that the writing of the line may proceed. If it should be desired, however, to adjust the paper in this manner so far forward or backward that the check spring-6 would be unable to re- 0- sition the platen, it is only necessary to fii'st cast off the detent roller 6 and put on the brake l9, whereupon the lever 25 may be operated to rotate the platen either forwardly or backwardly, as desired, the length of its stroke being determined by the adjustment of the screw 31, and either said screw or the opposite stop 29 being in contact with the platen frame at the beginning of the stroke, according to the direction in which it is desired to adjust the platen. After Writing the desired characters out'of line, the lever 25 may be given a reverse stroke, so as to re' store the platen toits original position. Then the lever 13 may be thrown down so as to re- ,engage the platen-positioning wheel 6 with the line space wheel5, whereupon the writing of the line may proceed.

It will be seen that I have combined with ordinary line feeding mechanism, including the ratchet Wheel or curved rack 5, means for releasing the paper from the control of 6c.

said .wheel or rack, and mechanism having a minutely adjustable throw for effective s ecial line-feeding movements of the paper, t e brake 19 frictionally opposing rotation of the platen. so as to prevent accidental movement of the paper in line feed direction; that the releasable detent 6 normally engages the platen-positioning wheel 5; that the screw 31 enables the throw of the reciprocatory clutch mechanism to be finely adjusted; that the ordinary line feeding mechanism is arranged at one end of the platen and the reciprocatorv clutch mechanism at the other end thereof; that the vibratory gripper-carrying. arm 22 is mounted concentrically with the platen; that the extent of movement ofthe paper at the operation of the chutch is mechanically determined that the clutch lever is operated independently of the lever 8 that rotates the line-space wheel; and that ,thejplaten may be adjusted in opposite directions by means of the clutch. I
